mhp exclusive scan much slower than inclusive (exclusive scan perf analyse)
When looking at benchmarks at borealis: https://github.com/intel-sandbox/libraries.runtimes.hpc.dds.dr-ci/actions/runs/6717195674

E.g. for last benchmark it is 5sec vs 346sec.
Check why it is so. For now I am disabling also mhp benchmarks.
